This universal tool allows you to calculate how many calories you burn during various exercises and activities. The calculator works in two modes: based on the MET (Metabolic Equivalent of Task) value and based on the known kcal/min burning rate. Just enter your weight, training duration and the appropriate parameter to receive the result in kcal and additionally conversion into minutes.
What the calculator is for
The calorie burn calculator is intended for everyone who wants to:
- estimate energy consumption during cardio training, strength training or daily activities,
- control the caloric balance in a reduction or mass diet,
- compare the intensity of various physical activities,
- enter more detailed data in training diaries or fitness applications.
How the calculator works
You can use two modes:
- Weight + time + MET- you enter the weight, training length and MET value of a given activity.
- Time + burning rate- you enter the duration of the training and the known kcal/min burning rate, e.g. from a smartwatch or from literature.
Calculation formulas
| Mode | Formula | Description |
|---|---|---|
| MET | Calories = MET × mass(kg) × time(h) | The MET value determines how many times activity increases burning compared to rest |
| Pace | Calories = rate (kcal/min) × time (min) | Simple conversion from the ready-made burn rate per minute |
Step-by-step instructions
- Select the calculation mode: MET or burn rate.
- Enter your body weight (for MET mode).
- Set the exercise duration in hours and minutes.
- For MET mode, enter the MET value, e.g. running 8 km/h ≈ 8.3 MET.
- For pace mode, enter the burning rate, e.g. 12 kcal/min.
- Click "Calculate" to see your total calories burned and calories per minute.
Usage examples
Running, 70 kg, 45 minutes, MET 10
Calories = 10 × 70 × 0.75 = 525 kcal. Per minute ≈ 11.7 kcal.
Indoor cycling, 80 kg, 30 minutes, MET 7
Calories = 7 × 80 × 0.5 = 280 kcal. Per minute = 9.3 kcal.
Smartwatch data: burning rate 13 kcal/min, time 20 minutes
Calories = 13 × 20 = 260 kcal.
Orientation table
| Activity | MET | Time (30 min) | Calories (70 kg) |
|---|---|---|---|
| Fast walking | 3.8 | 30 min | 133 kcal |
| Running 8 km/h | 8.3 | 30 min | 291 kcal |
| Intensive swimming | 9.5 | 30 min | 333 kcal |
| Jumping rope | 11.8 | 30 min | 414 kcal |
Frequently asked questions
Where to get the MET value?
You can use MET tables available in the scientific literature or online. MET describes the intensity of various activities.
Does the calculator take into account gender and age?
No, the result is an estimate based on body weight, time and intensity. Individual fuel consumption may vary.
Is kcal/min rate more accurate?
Yes, if it comes from a reputable monitoring device that measures heart rate and movement.
Practical tips
- If you do not know the exact MET value, choose an approximate one from the tables.
- Use the calculator to compare activities and plan your diet.
- Remember that real fuel consumption may differ from theoretical values.
Most common errors
- Giving too low a MET for intense activity - the result will be low.
- Inaccurate time - it is better to round to minutes rather than hours.
- Using a kcal/min pace without a reliable source.
